WebMar 6, 2024 · Installing a ground source heat pump is a large project , so you might expect to pay between $10,000 - $30,000 on a system. For smaller homes with lower heating and cooling loads, expect to be on the lower end of this spectrum. For example, a 2,000 square foot home will cost between $3,000 to $5,000 to install. WebFeb 9, 2024 · Outside of the property is a ground collector system made up of long lengths of pipework that are buried in trenches around 1.5meters deep. 50 m2 of ground will need to be trenched per kilowatt capacity of the heat pump. Therefore a 12kW heat pump would typically require around 600m2 of clear ground.
